Order of operations
PEMDAS
parethasees (inner to outer)
exponents
multiplication and division
addition and subtraction
remember thah yuo do all these left to right

so


[7-(2-5(4-2)+7)]+2
inner to outer
4-2=2

now we have
[7-(2-5(2)+7)]+2
multiply since no further parnthasees
2*5=10

now we have
[7-(2-10+7)]+2
add or subtract (subtraction is addition of a negative)
2-10=-8, and -8+7=-1

now we have
[7-(-1)]+2
last parenthsees/brackets
remember that subtracting a negative is the same as adding a positive
7-(-1)=7+1=8

now we have
[8]+2
add
10


yep, 10 is right

The entire graph of the function g is shown in the figure below.
marusya05 [52]

The domain of the function is [-4, 4) and the range of the function is [-5, 2)

<h3>How to determine the domain and the range of the function?</h3>

<u>The domain</u>

As a general rule, it should be noted that the domain of a function is the set of input values or independent values the function can take.

This means that the domain is the set of x values

From the graph, we have the following intervals on the x-axis

x = -4 (closed circle)

x =4 (open circle)

This means that the domain of the function is [-4, 4)

<u>The range</u>

As a general rule, it should be noted that the range of a function is the set of output values or dependent values the function can produce.

This means that the range is the set of y values

From the graph, we have the following intervals on the y-axis

y = -5 (closed circle)

y = 2 (open circle)

This means that the range of the function is [-5, 2)

What is the equation of the line that is parallel to y=6x−1 and passes through the point (−3,4)?
BabaBlast [244]

Answer: y = 6x + 22

Step-by-step explanation:

Parallel lines have same slope. So, a line parallel to y = 6x − 1 is y = 6x + c.

Now to find c, put (-3,4) to this equation since the line passes through the point.

4 = 6 × -3 + c

4 = -18 + c

4 + 18 = c

c = 22

So, equation is y = 6x + 22
